Geomechanics is a Russian software that can be used for geomechanics modelling of near borehole environment for determining mechanical properties and rock stress state based on well-logging data, well testing data and core investigations results.

About Geomechanics

Geomechanics software provides User the easiest way to predict the well mechanical behavior before-, while- and after drilling.
Geomechanics software includes all necessary tools for the following tasks:
  • Drilling risks reduction due to a reliable evaluation of the safe mud weight window, including wellbore instability intervals, AHRP, mud loss, etc.
  • Drilling problems prediction as an oil and gas showing, blow out, sticking, collapsing, sand production, overpull, landing of drilling bit, etc.
  • Well design optimization and correction of casing shoes depth landing
  • Optimal direction and angle of drilling determination
  • Real-time drilling support to increase rate of penetration, minimize downtime and inefficient construction costs
  • Optimization of hydraulic fracturing design

Input Data

Geomechanics software allows User to download and analyze all data that required for geomechanical modeling.

The LAS bootloader allows batch input of information with the specification of several criteria (certain logging methods, selected depths and wells).

Stratigraphy columns data, core analysis tables, well tests, lithology columns, mechanical facies, drilling complications are conveniently inputted through the clipboard using the most common office software.

Data Analysis

Geomechanics software has a complete set of utilities that allow User to properly prepare various data before Geomechanical modeling:
  • Merge, linking and other operations with log curves
  • Smoothing log curves
  • Petrophysical rock characteristics calculation
  • Values conversion of slowness to wave propagation velocity
  • Gradient-Pressure conversion, which allows you to recalculate pressure values in gradients and vice versa
  • Script editor allows User to create custom user modules, calculate the synthesis logs by various methods, etc.
For data analysis the Geomechanics software has at its disposal:
  • Well sections for displaying all types of data simultaneously for several wells and the possibility of constructing cross-well correlation schemes
  • Cross-plots for constructing various dependency graphs (as types as Core-Core, Core-Log, etc.), obtaining trend lines and correlation coefficients

1D-Geomecanhics Model

The Geomechanics software allows User to obtain the following results in the simulation:
  • Stress profiles (overburden pressure, pore pressure, fracture pressure, collapse pressure)
  • Dependence charts between dynamic and static elastic properties, profiles of static properties along a cross-section taking into account different lithological / stratigraphic intervals
  • Dynamic elastic properties (Young's modulus, Poisson's ratio)
  • Wellbore stability model (Mohr-Coulomb, Lade, Drucker-Pruger of combined criteria)
  • Safe mud density window taking into account the schedule pressures
  • Stereonets that allow User to determine the optimal mud weight for any drilling
  • Inclination and azimuth of Cross-well correlations

Morh Envelope
The most popular modules of Geomechanical modeling are:
  • Pressure analysis - allows to define formations with AHRP and lost circulation zones
  • Formation breakout analysis - allows to detect intervals of instability of the walls of wells, possible collapse zones while drilling
  • Stereonets - allow User to correct the mud weight taking into account the magnitudes and orientation of the principal stresses, determine the optimal angle of drilling and the direction of drilling of inclined and horizontal wells
  • Brittleness index - allows to allocate the most perspective areas for selection of sweet spot zones and barriers of fractures from the mechanical properties point of view
  • Hydraulic fracture analysis allows to control the maximum possible pressure in order to avoid hydraulic fracturing of rocks
  • Sand production analysis is an assessment of the potential sand production and pressure when this process can occur. This allows User to choose the correct methods for combating the destruction of the reservoir, such as the types of well completion, perforation design, selection of ground equipment
  • Morh-Coulomb envelope is based on the relationship between shear and normal stresses at each point of the rock. The module allows to determine the most optimal criterion of rock destruction on the basis of the core study results.
  • Properties propagation is a special Master allows to easily propagate the created geomechanical model from a drilled well to the project wells taking into account their trajectory and stratigraphy data
  • Script editor allows User to create your own custom modules, synthesize logs by various methods, perform petrophysical calculations, etc.

Geological Risks Analysis

Taking into account drilling problems, it allows User to assess the origin of geological risks and correct the geomechanical model.
Modeling in Geomechanics software allows User to minimize the possible risks associated with:
  • Wellbore instability
  • Determining the depths of landing shoes casing columns
  • The ES on the site (oil and gas showing, blow out, sticking, collapsing, etc.)

Multi-Well Mode

Multi-well mode makes it easier to work with large amount of data. Geomechanics software provides functionality for the automated calculation of 1D-geomechanical models based on the User-planned Scenario (Workflow).

Real Time Geomechanical Modeling

Geomechanics provides the Real Time Geomechanical Support for the drilling process utilizing WITSML standard. This is performed in collaboration with the mud logging stations "SNGS" and "Tetrasoft". The Real Time service implies daily reports along with comparison of the pre-drill geomechanical model to the real measurements.
